VALVED BUNG FOR BARRELS OR SIMILAR RECEPTAOLES.

SPECIFICATION. forming part of Letter's Pate-nt N0. 753,308, dated March1, 1904.

Application filed January 28, 1903.

To all whom, it may concern:

Be it known that I, JOHN E. PHILLIPS, a citizen of the'United States,residing in the city of J oliet, in the county of Will and State ofIllinois, have invented certain new and useful Improvements in ValvedBungs for Barrels is a specification.

My invention relates to valved bungs for metallic barrels, casks, kegs,tuns, and similar receptacles. Its object is to provide eflicient andcommercially practical means of comparatively slight cost to manufacturefor reinforcing bung-holes, means for closing bung-holes, and apressure-controlled bunghole valve.

Referring to the accompanying drawings, wherein like reference-lettersindicate the same or corresponding parts, Figure l is a fragmentary planview. Figs. 2 and 4 are fragmentary sectional views, partly shown inelevation; and Fig. 3 is in part a cross-sectional and in part a planview of certain of the parts shown in Figs. 2 and 4.

In the drawings, A is a metallic barrel, cask, or other receptacle; B,an interior-lythreaded bushing; O, a bung-hole slide-valve; 0, guidemembers forming a part of or secured ing a part of said valve andpreferably provided with screw-threads 0 adapted toengage or to beengaged by a suitable nut 0 D, a substantially annular valve-seat memberprovided with exterior screw-threads d, adapted to engage thescrew-threads b on the interior of the bushing B; cl, spoke-like arms Dand preferably connected one to'another at their point of juncture; J,an aperture or hole adapted to receive the pin 0; d guide slots,channels, or grooves in the interior facev of the member D, adapted toreceive the guide members 0; E, a plug or-bung provided withscrew-threads 6, adapted to engage or to be engaged by the threads 5; a,an annular groove in the lower face of the plug adapted to receive theends a of the members 0 when the valve O is in closed position and theplug in place substantially as shown in Fig. 2; F,

a spigot or cook of any suitable type provided Serial'll'o. 140,923. (Nomodel.)

with screw-threads f, adapted to engage or to be engaged by, the threads5; G, a leaf-spring adapted to exert a pressure upon the valve C toclose the-same and preferably secured by a rivet or other suitable means9' to the valveseat member D.

Assuming the parts shown in Fig. 2 to be in the position thereinillustrated and the barrel to contain fluid under sufiicient pressure tohold the valve C in closed position firmly seated against the valve-seatmember D, to permit the escape of any desired quantity of the fluid fromthe barrel the plug D must first be removed from the bushing B, which iseffected by screwing said plug out of said bushmoval of the plug fromthe bushing or to secure the same properly therein. Assuming the plug Eto be removed from the bushing,

a portion or substantially the whole of the fluid under pressure withinthe barrel may be removed by unseating the valve O, thus establishingcommunication between the inside of the barrel and the atmosphere or asuitable pipe or receptacle. To open the valve C, it is but necessaryfor the operator. to inwardly press against the pin 0 or against the end0 of one or more of the guide members a with suflicient force toovercome the pressure within the barrel. When this pressure is overcome,the valve will be moved backward until its further movement in thatdirection is prevented by the nut 0 coming into contact with the membersd at or substantially at their point of juncture. When said valve andthe partscarried by it are backwardly moved, as described, they willassume substantially the position shown in Fig. 4, whereupon the fluidwill pass, by reason of the pressure within the barrel, between thevalve and the valve-seat and escape through the bung 4 hole. This methodof opening the valve may be employed where the nature be employed toremovepr to facilitate the reof the fluid or quasi fluid will sowarrant. Where, however, the fluid is under pressure,

which pressure it is desired to maintain so far.

. members 0, and upon being farther screwed be moved backward into openposition.

into the bushing will inwardly press against said members, therebycausing the valve C to In the drawings only a portion of the cock isshown, as it will be understood that any suitable cock closing oropening means, as a wheel or handle and a turn or lift valve, may beemployed to control the discharge of fluid proceeding from thereceptacle. When the fluid within the barrel is under suflicientpressure, said pressure will cause the valve to close if the pressureexerted by the operator to open the valve be discontinued or if the cockor plug E be sufficiently unscrewed to permit of the valve being movedoutwardly by pressure or by gravity until it shall firmly bear againstits seat. Where the fluid is not under pressure any suitable mechanicalpressure means, as a spring, may be employed to hold the valve normallyseated for example, the spring G. When the fluid within the barrel isunder pressure or is of a nature, as is gas, to itself exert apressure'and the spring G is employed, it will at once be seen thatthecombined pressure of the spring and of the pressure within the barrelwill effect a seating of the valve C, when said valve is free to move toits seat.

In constructing the receptacle a certain opening is first made in thehead or other part of the receptacle at the point where the bushing isto be located. The diameter of this opening is smaller than that of thefinished bunghole, and the bung-hole proper is subsequently formed bypressing the edges of the original opening downward into the receptacle,so as to form the circumferentially-continuous flange a, which is of onepiece with the head of the receptacle. By preference said flange issubstantially cylindricalthat is to say, extends substantially at rightangles to the adjacent portion of the receptacle. The bushing B conformsto the receptacle at the bung-hole and has an annular flange b, whichmakes contact with and rests upon the outer surface of the receptaclearound said bung-hole, said bushing therefore constituting acentrally-apertured cap closely fitting into the bung-hole. The depth ofthe bushing is greater than the depth of flange a, and in securing thebushing in position the inner extremity thereof (shown in dotted lines,Figs. 2 and 4) is beaded over or set back, as shown in full lines andmarked 6 in said figures, to engage the innermost extremity (0 of saidflange a. It will be readily understood that this heading over orsetting back of the inner extremity of the bushing operates to draw thebushing down firmly in position upon the exterior surface of thereceptacle at the bung-hole, and consequently insures a hermetic sealingof the bushing to the receptacle. The flange a is under compressionbetween the upwardly-straining upper surface of beading Z2 and thedownwardly-straining lower surface of the flange 6. The bushing isextended to form a permanent part of the receptacle and greatlystrengthens and stiffens the parts thereof adjacent to the bung-hole.After the bushing has thus been secured within the bunghole proper thevalve and valve-seat may be assembled in proper position, substantiallyas shown in Figs. 2 and 4:, by first securing the valve to the seat byinserting the pin 0 within the hole cl" and the guide members 0 withinthe grooves and then screwing the nut 0 upon the pin and thereafterscrewing the valve-seat member carrying the valve into the bushing. Whenit is desired to fill a barrel equipped. with the valve, said valve maybe held open in any suitable manner and the barrel-filling materialintroduced through the bung-hole. When said barrel is to be filled bypressure means of suflicient strength to open the valve and to hold itopen, no other means need be employed to unseat the valve and hold it inopen position. When the spring G is omitted if the barrel be in properposition and not under internal pressure suflicient to hold the valveclosed the valve will be open by gravity; so, too, when the materialwith which it is desired to fill the barrel is of suflicient weight toovercome the frictional resistance offered by said valve or the pressureexerted upon the valve to keep it closed. Hence it will be seen I haveprovided a valve which may be opened manually, by gravity, or bypressure means and which may be closed either by spring or fluidpressure means, or both.

It is obvious that instead of employing a cock which when screwed intothe bushing will come into contact with the guide members 0 upon thevalve said cock may bear against the pin 0 or nut 0 or that anadditional member may be employed against which said cock will bear,said member in turn bearing in any suitable manner against said valve ora projection or projections thereon. It is further obvious that theremay be as many arms 0? as preferred and that where two or more areemployed and convergently disposed they need not meet; that instead ofemploying said arms any suitable means may be employed to limit thedistance traveled by the valve 0 in being opened and to retain saidvalve when opened in such position that it may be moved into closedposition; that instead of the pin 0 and nut 0 any suitable stop meansmay be em ployed to limit the movement of the valve C;

' bung-hole be made of metal.

that, if desired, the groove 6' maybe omitted;

that any suitable form or type of spring may be employed to accomplishthe purpose of the spring G or that said spring may be omitted; thatthere may be as many guide members 0 as desired, that instead of aportion of the spigot projecting into the bung-hole or the hole withinthe bushing and against the valve 0 or a projection or projectionsthereon a suitable pipe or tube or other suitable hollow member may beemployed to effect the same ends, and that this pipe may or may not becontrolled by a spigot or valve, as preferred; and it is still furtherobvious that the number, size, and form of the various 7 parts of mydevice and the location of certain of said parts may be greatly variedwithout departing from the principle of the invention.

Although ordinarily the entire receptacle will be made of metal, I donot wish to be limited to a receptacle so constructed. So far as myinvention is concerned it is essential only that the portion surroundingthe For example, if the bung-hole be located in the-head of thereceptacle the head only may be of metal, and the sides thereof mayunder certain circumstances be of wood, wood-pulp, or other material.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a receptacle havinga metallic bung-hole, the edgeswhereof are turned in to form a flange, and a one-piece metal bushinghaving an annular flange adapted to rest upon the exterior surface ofthe receptacle around the bunghole,and said bushing being beaded overupon the innermost extremity of said receptacle-flange whereby saidreceptacle-flange is retained between two opposing annular surfaces ofsaid bushing for the purpose described.

2. The combination, with the remaining.

bushing being beaded over the innermost extremity of saidreceptacle-flange whereby the receptacle is held between opposingsurfaces of said bushing.

3. The com bination of a receptacle having a metallic bung hole, theedges whereof are turned in to form a flange; a one-piece metal bushinghaving an annular flange adapted to rest upon the exterior surface ofthe receptacle around the bung-hole and said bushing being beaded overupon the innermost extremity of said receptacle-flange whereby saidreceptacleflange is retained between two opposing annular surfaces ofsaid bushing; and a slide-valve controlling the hole in said bushing.

4:. In combination, a receptacle, the bunghole portion whereof is ofmetal; a bung-hole in said receptacle, a bushing secured within saidbung-hole and reinforcing the wall thereof; a valve-seat member securedwithin said bushing at the lower portion thereof, said valve seat memberbeing provided with grooves; a slide-valve movable in and seating uponsaid valve-seat member; guide members formed on said slide-valve andguided by the grooves in said valve-seat member; said guide membersextending above the top of the valveseat memberwhen said valve isseated; and a spigot, one end of which is adapted to be inserted intothe bung-hole for engaging the guide members on said valve to open saidvalve; and means for closing said valve.
